Short answer: The best one is the one that works where you are. In the US, Gemini's Call for me suits Pixel 10 and 11 owners with a Google AI plan, and Grok Bot suits SuperGrok subscribers. If you are in Canada, the UK or Australia, or want calls from ChatGPT, Claude or another app you already use, a calling connector such as OsmO is the practical route, and it starts free.
Three questions decide it: which country, which phone, and which AI app you already use.
Built-in callers reach US numbers only today; OsmO calls businesses in your own country if you live in the US, Canada, the UK or Australia.
Give the AI a clear brief: the business, the question, and what you would accept.
Keep card numbers and passwords out of the request; finish payments yourself.
How it works
- Sign in with your mobile numberYou get 50 free credits. Nothing to pay.
- Add OsmO to your AI appChatGPT, Claude, Grok and other apps that take connectors.
- Ask it to callOsmO calls, talks, and tells you what was said.
The full guide
Pick by your situation
| If you… | A good fit |
|---|---|
| Have a Pixel 10 or 11 in the US and a Google AI plan | Gemini's Call for me |
| Pay for SuperGrok or Cursor Pro | Grok Bot, included with those plans |
| Only need a price quote from US local services | Google Search's AI price check |
| Live in Canada, the UK or Australia | OsmO in ChatGPT, Claude, Grok or another connector app |
| Already do your planning in ChatGPT or Claude | OsmO, so the call happens in the same chat |
| Only want to skip the hold queue yourself | iPhone Hold Assist or Pixel Hold for Me |
None of these is the right tool for everything. If you are in the US with the right Pixel and plan, Gemini is already on your phone and calls from your own number, which some businesses prefer. OsmO calls from the OsmO number for your country instead.
If none of the built-in options fit, that is the normal case rather than the exception: most people are outside the US, on a phone other than a recent Pixel, or not paying for an AI plan that includes calling.
Calls worth handing to an AI
- Questions with a short answer: opening hours, stock, prices, whether a slot is free.
- Bookings and changes: a table, a haircut, a dentist's cleaning, moving an appointment.
- Long queues: airlines, utilities, insurers and government lines, where most of the call is waiting.
- Comparisons: the same question to several places. In ChatGPT, Claude, Grok and other connector apps, OsmO takes up to five numbers in one request.
We have step-by-step pages for common ones, such as calling an airline and booking a restaurant.
Whichever you pick, keep the first few calls simple and check the answers against what you expected. Once a tool gets the easy calls right, hand it the slow ones: the queue at the airline, the insurer, the council.
How to brief your AI
An AI caller is only as good as the request you give it. Brief it the way you would brief a friend calling on your behalf:
- Name the business and the area, or give the number if you have it. Your AI app, or OsmO itself in ChatGPT, Claude, Grok and other connector apps, looks up the listed number.
- Say what you want in one sentence.
- Add the details the business will ask for: a name, a booking reference, a date.
- Say what you would accept if the first answer is no, such as another time or a different size.
- Say what not to agree to, such as paying a fee.
Mistakes that waste a call
- A vague goal. "Ask about my order" leaves the AI guessing. "Ask when order 4471 will ship" gets an answer.
- No backup. If the first time is taken and you gave no alternative, the AI has to come back to you.
- Missing details. Businesses ask for a name or a reference first. Put them in the request.
- The wrong branch. A chain with many locations needs the area or street, or the AI may ring the wrong one.
None of these cost much with OsmO, since a call nobody answers is free and a short answered call uses the same 3 credits as a long one. But a clear first brief saves you a second call and gets you the answer sooner.
What to keep for yourself
Some calls are better made in person. If a business wants a card number, a password or a security answer in your own voice, the AI should stop and hand back to you. Gemini's Call for me rules out payments and sensitive personal information too. And for anything urgent, call the emergency number yourself.
Keep card numbers out of the request. If a call needs a payment, finish that part yourself.
What OsmO costs and where it calls
OsmO For my AI starts with 50 free credits when you sign in with your mobile number, with no card. An answered call uses 3 credits however long it lasts, and a call nobody answers is free, so the free credits cover about 16 answered calls. When they run out you can keep calling from the OsmO app.
You can sign in with a mobile number from the United States, Canada, the United Kingdom or Australia (India too), and calls are placed from the OsmO number for your country. From an AI app, OsmO calls listed businesses and toll-free helplines in your own country. With the OsmO app, it can also call your saved contacts. It works phone menus and waits on hold, and a long hold costs the same 3 credits as a short call.
Questions people ask
Can an AI call a business and book an appointment?
Yes. Give it the business, the kind of appointment and the times you can do, and it asks for a slot and reports back what was agreed.
Will the business know my number?
With OsmO, the call comes from the OsmO number for your country, not your own. Gemini's Call for me uses your own number.
Can I have the AI call my landlord or a friend?
Yes, if they are in your saved contacts and you use the OsmO app, which syncs your contacts. With only the free web credits, OsmO calls listed businesses and toll-free numbers.
